If your worried about spooking deer off your feeder than try this. As long as you can get there without them smelling you, just use your flashlight and shine it at your feeder and /or any deer that you hear running off. But stay as quiet as possible. The light doesn't seem to spook them but just runs them off and keeps them curious. I have done this several times on mature bucks which have run off but soon returned just 20 minutes later like nothing has happened.
Hmm. If they can't smell me, then I'd rather try to be as stealth as possible to get to my stand. I know mature bucks that usually if once hit by an infrared cam light do not return so I'm not sure about hitting them with my flashlight. However, I do know they are curious... just crank up chainsaw for camp wood and in a minute look around and see who's watching.
